Refrigeration appliance comprising an ice and/or liquid dispenser

ABSTRACT

A household refrigeration appliance includes a housing with several walls that have an insulating layer and surround an interior to be cooled, and/or at least one door that has at least one insulating layer. A recess that is accessible from outside is provided in a wall of the housing and/or in the door. In the area of the recess, the wall and/or the door is fitted with at least one heat-insulating element which has a lower thermal conductivity than the insulating layer of the wall and/or door.

The invention below relates to a refrigeration appliance, in particulara household refrigeration appliance, having a housing with several wallsthat have at least one insulating layer and enclose an interior space tobe cooled, and/or having at least one door that has at least oneinsulating layer, with a recess that is accessible from outside beingprovided in a wall of the housing and/or in the door.

In the region of the recess or cutout for the ice and/or liquiddispenser of a refrigeration appliance, in particular of a householdrefrigeration appliance, said recess or cutout being accessible fromoutside, the inner wall of the housing and/or door is generally offsetin the direction of the interior space of the refrigeration appliance inrelation to the remainder of its inner wall surface, in other words inthe region of the recess the inner wall of the housing and/or doorprojects into the interior space of the refrigeration appliance inrelation to the remainder of the inner wall surface. The wall of thehousing and/or door, which projects inward locally in the region of therecess or indentation reduces the interior space available. The recessor indentation in the wall and/or door also brings with it a risk ofunwanted energy losses.

The object of the invention is to provide a refrigeration appliance, inparticular a household refrigeration appliance, with a recess for an iceand/or liquid dispenser with improved energy efficiency.

This object is achieved with a refrigeration appliance, in particular ahousehold refrigeration appliance, of the type mentioned in theintroduction in that the wall and/or door features at least oneheat-insulating element in the region of its recess, said heatinsulating element having a lower thermal conductivity than itsinsulating layer.

This permits the thermal insulation in the region of the recess of thewall and/or door of the refrigeration appliance, in particular householdrefrigeration appliance, as provided for its ice and/or liquiddispenser, to be improved. For example the wall thickness of the walland/or door in the region of its recess can be selected to be thinnerthan where there is no heat-insulating element. This means on the onehand that less interior space is required for the wall and/or door. Onthe other hand adequate thermal insulation of the recess can be achievedin relation to the cooled interior space. This reduces or prevents forexample the formation of condensation moisture in the recess, inparticular on a rear face of the recess. Also the wall structure and/ordoor structure in the region of the recess can be simplified due to theat least one heat-insulating element.

In a preferred embodiment the insulating element is configured as avacuum element, in other words as an element in which a hollow spacecontaining a vacuum is provided. The vacuum permits very good thermalinsulation of the recess even if the vacuum element is not very thick.The wall thickness of the wall and/or door in the region of the recesscan therefore be configured as thin due to the one or several vacuumelements, in order to achieve adequate insulation.

According to one expedient development of the invention theheat-insulating element is configured in the form of at least one plate,which covers at least a rear wall of the recess partially or completelyon the inside and/or outside, or completely or partially forms saidwall. This allows improved thermal insulation to be achieved in theregion of the recess or cutout in a structurally simple manner, suchthermal insulation being provided for the ice/liquid dispenser in ahousing wall and/or door of the refrigeration appliance.

The heat-insulating element can advantageously adjoin the recess and canbe covered on the inside and/or outside with at least one foamedinsulating layer. This produces a composite insulating materialstructure which features a sufficiently high thermal insulation capacityeven with a small overall layer thickness.

It may in particular be expedient if the one or several heat-insulatingelements are tailored partially or completely to the respectivelydesired inner contour of the recess in respect of their geometric shape.This allows the hollow space of the recess to be enclosed or framed, inparticular to be lined on the side of the inner wall, partially orcompletely with at least one heat-insulating element in a particularlysimple manner. The respective heat-insulating element here functions asa cladding part for the recess on the side of the wall or door facingthe interior space of the refrigeration appliance.

To this end it may be advantageous for the heat-insulating element to beconfigured for example as a curved plate, which partially or completelycovers a rear wall and two side walls of the recess on the inside and/oroutside or forms this completely or partially.

Alternatively it may in particular be expedient for the heat-insulatingelement to be configured as a twice angled plate, in particular a platethat is angled so that it is trapezoidal in cross section, partially orcompletely covering a rear wall and two side walls of the recess on theinside and/or outside or forming this completely or partially.

In general terms therefore according to one advantageous development ofthe invention the inner surface of the recess is covered completely orpartially by one or several heat-insulating elements and/or the one orseveral outer walls of the recess are formed by one or severalheat-insulating elements. On the one hand the heat-insulating element ineach instance can thus be provided partially or completely as anadditional cladding part or sheathing part on the inner faces of one orseveral outer walls of the recess. To this end it is expedientlypositioned from the rear, i.e. on the interior space side on the innerface of the respective housing wall or the inner face of the outer wallof the door in the region of the recess. On the other hand it mayalternatively also be expedient for the heat-insulating element in eachinstance partially or completely to form one or several outer walls ofthe recess per se. The respective heat-insulating element can thenadvantageously replace the hitherto present outer wall of the recess,thereby simplifying the structure.

It may in particular be expedient for the respective heat-insulatingelement to feature a greater rigidity than the insulating material layerin the interior of the housing wall or door of the refrigerationappliance. This gives the region around the recess sufficient mechanicalstability, in other words loading capacity, for the recess to be able towithstand mechanical stresses due to the installed ice/liquid dispenserand other loads to an adequate degree.

It may in particular be expedient for the heat insulating element toadjoin the recess or partially or completely form its outer wall and tobe covered on the inside and/or outside with at least one, preferablyfoamed, insulating layer. This advantageously provides a compositestructure with the inside insulating material layer of the respectivewall or door, which is largely mechanically stable while at the sametime having further improved thermal insulation capacity.

In a further advantageous embodiment the heat insulating element isdisposed at least on a rear wall of the recess. It preferably covers theentire rear wall of the recess. The rear wall of the recess is acritical region in respect of the transfer of heat, so the fact of itbeing covered by the heat-insulating element permits effectiveinsulation of the recess.

In a further expedient embodiment the heat-insulating element alsocovers two opposing side walls of the recess in addition to the rearwall. This further improves the thermal insulation of the recess. Theelement here can preferably be configured as a curved plate. Use of thecurved plate in particular has the advantage of low-cost production ofthe heat-insulating element.

In a further expedient embodiment the element has the shape of a twiceangled plate, with the rear wall and two opposing side walls of therecess being covered. This additional lateral framing ensuresadditionally optimized thermal insulation of the recess. The angledshape of the plate permits the essentially cuboid recess to be coveredand insulated by means of the element in a space-saving manner.

In a further expedient embodiment a dispenser is provided above therecess, the element reaching up to the dispenser but leaving it freelyaccessible, in other words not covering it.

In a further expedient embodiment the wall of the housing or door has atleast one heat-insulating element and a layer of insulating material inparticular on the rear face of the recess, also covering other surfaceregions of the wall of the housing and/or door. The arrangement of theinsulating layer in addition to the heat-insulating element allows thethermal insulation to be increased. Alternatively the element can beembedded in the insulating layer, optionally all round it. This improvesthe thermal insulation overall.

In a further expedient embodiment the element is fastened to an innerface or rear face of the rear wall and/or the respective side wall ofthe recess with the aid of an adhesive connection, in particular withdouble-sided adhesive tape. This type of fastening is simple to executeand permits the application, in particular foaming, of the insulatinglayer on a rear face of the heat-insulating element and in furtherregions of the wall of the housing and/or door.

In one preferred embodiment the recess is disposed in a door, inparticular in a wing of a double door, which serves to close off theinterior space of the housing. This embodiment is particularly suitablefor built-in refrigeration appliances, with which only the door isaccessible from outside.

In a further embodiment the insulating layer is configured thinner onthe rear face of the heat-insulating element than in regions offset tothe side of the recess or above and/or below it. It is thereforepossible to reduce the space required by the recess in the interiorspace of the refrigeration appliance.

Elements of identical function and mode of operation are shown with thesame reference characters respectively in FIGS. 1 to 8.

FIG. 1 shows a schematic diagram of a household refrigeration appliance1, which has a heat-insulating container 2. The household refrigerationappliance can be configured for example as a refrigerator, a freezerand/or a combined refrigerator and freezer. Its container 2 has walls 3,which enclose at least one interior space. It comprises two side walls,a rear wall, a top element and a bottom element, thereby forming apreferably approximately cuboid container with a front access opening.In the present exemplary embodiment this can be closed off by twopivotable doors 4. The two doors 4 are configured in the form of wingdoors which are supported in a pivotable manner on the housing of thecontainer 2 on the outer faces. The container 2 has a multilayeredstructure. It comprises a box-type inner container IB that is open atthe front and has a thermal insulating material layer IM around it onthe outside. This is enclosed by a box-type outer housing AG that isopen at the front and forms an outer cladding part. In FIG. 1 the innercontainer IB and the insulating material layer IM are simply indicatedwith a dot-dash line. The inner container is preferably produced bydeep-drawing one or several plastic plates. It encloses an interiorspace with at least one refrigeration compartment and/or freezercompartment. The respective door is also structured in a similar manner,in other words it has an insulating material layer 22 between its innerwall shell IS and its outer wall shell AS (see FIG. 6 for example). Theinsulating material for the respective insulating material layer can beconfigured as PU foam (polymethane) for example.

An essentially rectangular recess or cutout or indentation 5 is let intoone of the two doors 4, it being possible to position a vessel forholding ice and/or chilled liquid, in particular water, therein. Therecess 5 is bounded by two side walls 6, a rear wall 7, a top wall 26and a grid 13 in a bottom surface. The recess 5 could also be let into aside wall 3 of the container 2. The respective door 4 in each instancehas an inner intermediate layer 22 of thermally insulating material,which fills the hollow space between its inner wall shell or innerlining IS and its outer wall shell AS, in order to insulate the interiorspace of the household refrigeration appliance 1 thermally from itsenvironment. The insulating material can be configured as PU foam(polymethane) for example. The recess 5 can also be closed off by way ofa sliding door or flap, depending on the selected embodiment. The recess5 is accessible from outside so that chilled liquid, in particularwater, and/or ice can be removed from the household refrigerationappliance 1 by means of an ice/liquid dispenser without the door 4having to be opened. The chilled liquid or ice can be dispensed forexample by way of a corresponding input using operating elements 24,which are disposed on the door 4, or automatically by positioning thevessel in the recess 5.

To produce the ice an automatic ice maker for example is provided in thehousehold refrigeration appliance 1, having a collector for preparedice, which is conveyed into the recess 5 by way of an ice chute and adispenser.

Instead of or in addition to the ice maker the household refrigerationappliance may also have a cooling facility for liquid, for example wateror juice, which dispenses liquid into the recess 5 by way of thedispenser.

FIG. 2 shows a schematic diagram of the inner face 9 of the outer wallshell or outer housing wall AS of the door 4 in the region of the recess5 viewed from the interior space of the household refrigerationappliance before the application of the insulating layer 22 and theinner wall shell IS. On the face of its rear wall 7 facing the interiorspace and the two side walls 6 the recess 5 is enclosed by an additionalcladding part in the form of a thermally insulating element 10.Alternatively the rear wall 7 and/or the two side walls 6 of the recess5 can also be formed solely by the thermally insulating element 10. Inthe exemplary embodiment in FIG. 2 the thermally insulating element 10is configured in the form of a curved plate or panel. The two narrowlateral end edges 11 of the plate, which is curved in particular in themanner of a shell and preferably in the manner of a partial cylinder,are fastened to the inner face 9 of the outer housing wall AS, saidplate covering the two side walls 6 and rear wall 7 of the recess 5.Optionally only part of the rear wall 7 and/or part of the side walls 6may be additionally covered by the thermal element 10 and/or formed bythis, depending on the selected embodiment. Alternatively it may in someinstances be sufficient only to additionally provide the thermallyinsulating element 10 in the region of the rear wall 7 or for this toform the rear wall 7 of the recess 5. The material selected for thethermally insulating element 10 is in particular a thermally insulatingmaterial that features a lower thermal conductivity than the insulatingmaterial of the inner intermediate layer 22 of the door 4. In onepreferred embodiment the thermal element 10 is configured in the form ofa vacuum element, in particular a vacuum panel. The thermal element 10here is made of plastic for example and has at least one hollow space inwhich the pressure is lower than atmospheric pressure. In particular avacuum may be present in the thermal element 10, being up to 90% belowatmospheric pressure or lower. In a further advantageous alternativeembodiment the hollow spaces of the thermal element 10 may expedientlybe filled with a thermally insulating gas.

The bottom face of the recess 5 in FIG. 2 is covered with a grid 13, toallow liquid to be conducted away as required, if it sprays to the sideof a drinking vessel as it is being filled. An ice/liquid dispenser 12is provided above the recess 5, it being possible for the housing of theice/liquid dispenser 12 also to form the top wall 26 of the recess 5.The dispenser 12 has a supply line connector 14 for the chilled liquid,which projects into the recess 5. The dispenser 12 also has a feedopening 15 for supplying and ejecting ice cubes into the recess 5. Thesupply opening 15 can be closed off with a flap (not shown), which isheld in a closed position with the aid of a spring and opensautomatically when ice is fed to it and dispenses the ice into therecess 5.

To produce the door 4 the free, inner surfaces 9 of its outer housingwall or front wall AS are covered with an insulating material, inparticular PU foam, to form an insulating layer 22. A rear wall or innerwall lining IS is then applied to the insulating layer 22 and connectedto the front wall AS. The insulating layer can be applied in the form ofa foam which hardens or as a solid material in the form of plates.According to a first advantageous variant the rear face and side wallsof the recess can remain free of the insulating layer.

According to a second expedient embodiment the rear face of thethermally insulating element 10 and the further free regions of the rearsurface 9 of the outer housing wall AS are covered with the insulatinglayer 22 (see FIG. 6). In a further advantageous embodiment thethermally insulating layer 22 rests on the inner face of the thermallyinsulating element 10 of the recess 5 and on the further free, innersurfaces of the inner face 9 of the outer housing wall AS. This allowsthe thermally insulating element 10 to be embedded in the insulatinglayer 22 in a largely form-fit manner.

The end edges of the thermal element 10 are connected to the innersurface 9 of the outer housing wall AS by way of an adhesive connectiondepending on the selected embodiment. An adhesive tape for example thathas an adhesive action on both sides can be used for this purpose.

In a further embodiment the bottom of the recess 5, which is coveredwith the grid 13, and/or the rear face of the dispenser 12 can also becovered up to its feed opening 5 with the thermally insulating element10 or with at least a further additional thermally insulating element10. Such measures further improve the thermal insulation in the regionof the recess 5. Instead of a single thermal element 10, severalthermally insulating elements 10 can also be provided, coveringdifferent regions of the recess 5. The thermally insulating elements 10can also have different thermal conductivities. For example a thermallyinsulating element covering a side wall 6 can have a higher thermalconductivity than a thermal element covering the rear wall 7 of therecess 5 from the rear.

FIG. 3 shows a schematic diagram of the perspective view of a detail ofthe thermally insulating element 10 from FIG. 2. It is configured in theform of a curved or arched plate. The lateral end edges 11 of the curvedplate are covered with an adhesive tape 19 that is adhesive on bothsides and ensures fastening to the inner surface 9 of the outer housingwall AS. The curved plate is configured in particular as a claddingelement in the manner of a shell or in particular in the manner of apartial cylinder.

FIG. 4 shows a further embodiment of a thermally insulating element 10in the form of an angled plate 16, which covers two side surfaces 6 andthe rear wall 7 of the recess 5. The plate 16 has a flat base plate 18and two flat partial plates 17 angled from it at the sides. It ispreferably configured as a single piece. Viewed in cross sectionperpendicular to the rear inner surface 9 of the outer housing wall ASit is configured in the manner of a U profile with arms splaying out, inother words its putative enclosing end is configured as trapezoidal. Theangled plate 16 allows the cuboidal recess 5 to be covered in arelatively close-fitting manner. In this embodiment too the thermalelement 10 can be connected to the rear wall 7 and/or the side walls 6of the recess by way of adhesive connections. A double-sided adhesivetape can also be used as the adhesive connection. The recess 5 can alsotaper conically inward for example so that its side walls 6 run parallelto the angled partial plates 17 of the thermally insulating element 10.This results in a largely close-fitting layering or stacking of the wallparts of the recess 5 and the one or several thermally insulatingelements 10 positioned, in particular adhered in place, from the rear.This on the one hand produces adequate thermal insulation for the regionof the recess. It also allows the recess in some instances to beembodied with a large degree of mechanical stability. To this end it canin particular be expedient for the respective, additionally provided,thermally insulating element to be configured with greater materialrigidity than the insulating material layer of the door.

FIG. 5 shows a schematic diagram of a perspective view of a detail ofthe thermally insulating element 10 from FIG. 4. It has the shape of atwice angled plate 16, the angled partial plates 17 being aligned at anangle greater than 90° to the base plate 18, producing a trapezoidallyextended, half-shell type cladding element. In the illustrated exemplaryembodiment a double-sided adhesive tape 19 is applied to the inner faceof the partial plates 17, the base plate 18 and the end edges of thepartial plates 17 facing the inner surface 9 of the rear face of theouter housing wall AS.

FIG. 6 shows a cross section through a finished door 4 viewed from theside in the region of the recess or indentation 5, the boundary walls 6,7 of which project further into the interior space 28 of the innercontainer IB of the household refrigeration appliance 1 than the otherinner surfaces 9 of the outer wall shell AS of the door 4. In thisembodiment the thermally insulating element 10 is only applied directlyto the rear wall 7 of the recess 5. The thermally insulating element 10extends essentially from the top wall 26 of the recess 5 down to abottom plate 21, which is disposed below the grid 13. The door 4comprises the outer housing wall AS and the inner housing wall IS, withthe layer 22 of insulating material inserted therebetween. The outerhousing wall AS and the inner housing wall IS can be made of plastic. Inthis embodiment the insulating layer 22 is also disposed in the regionof the recess 5 and in the region of the dispenser 12. In a furtherembodiment a thinner layer of the insulating material may be sufficientin the region of a rear wall of the recess 5 than in other regions ofthe inner surface of the door 4. Use of the additionally heat-insulatingplate in the region of the recess and the dispenser combined with athinner insulating material layer is sufficient in a plurality ofpractical circumstances to insulate the door perfectly in the region ofthe recess 5.

In the exemplary embodiment in FIG. 6 the thermal element 10 istherefore covered with a thinner layer 22 of insulating material thanregions of the door to the side of and/or above and/or below the recess5. The channels to the feed opening 15 and to the supply line connector14 in the region of the dispenser 12 are kept free in the layer 22 inorder to be able to connect the corresponding lines or the ice chute ofthe ice/liquid dispenser.

By configuring the thermal element 10 with a thermal conductivity thatis lower than that of the material of the insulating material layer 22it is possible generally to achieve a thinner structure of the door 4 inthe region of the recess 5. Adequate insulation of the recess 5 in theregion of the rear wall 7 and the side walls 6 of the recess 5 is stillensured however, so little or no defrost water can form there.

FIG. 7 shows a further advantageous embodiment, in which the thermallyinsulating element 10 is not disposed in direct contact with the wallparts 6, 7 of the recess 5 but at a distance with an intermediate spacebetween it and said wall parts 6, 7. The insulating material 22 is alsodisposed in this front intermediate space between the thermallyinsulating element 10 and the wall parts 6, 7 of the recess 5. Theinsulating material 22 rests on the rear face of the thermallyinsulating element 10 in the manner of an insulating jacket. This meansthat the thermal element 10 is covered with the thermally insulatinglayer 22 on both sides, in other words on its front face in thedirection of the recess 5 and on its rear face in the direction of theinner shell IS. It is in particular embedded completely in theinsulating material layer 22 and sheathed by this.

However in some instances it may alternatively also be sufficient toomit the insulating material layer 22 at the front or rear in the regionof the thermally insulating element 10.

FIG. 8 shows a view from the rear of a door 4 with a front housing wallAS, into which the recess 5 is let, in particular being molded therein.The recess 5 is covered with the thermally insulating element 10 on itsrear wall 7 at least. The thermally insulating element 10 is embedded inthe insulating layer 22, on the rear face of which the inner shell IS ispositioned. The thermally insulating layer 10 can be configured as aflat plate, a curved plate, an angled plate or in the form of severalplates.
